No. 25417 1 Claim.{(Cl.:57-36,)

This invention relates to spinning frames lwherein-a slubbing, roving,or sliver feedingpart and/ or .a slubbing, roving, or sliver drafting.part areor is enclosed in a chamber formed by a cover and cut off fromoutside .air, in said chamber is maintained at a temperature and ahumidity suitable for spinning.

In spinning factories, it isa commonpractice'to efi'ect air conditioningsuch. that .air'throughout a'large. space is maintained at .atemperature and humidity suitable for spinning. It is,'therefore,impossible to locally maintain the air surrounding the roving or sliverfeeding part and/or drafting part of the spinning frame at thetemperature and humidity most suitable for. spinning.

The above air conditioning to be effected throughout 'the large spacerequires not only installation and much expenses, but also results inadherance of flying and dust to sliver while it is spun, thus renderingproduction of yarn having improved. quality difficult.

An object of my invention is to obviate the above disadvantages and spinan improved yarn in an extremely economical manner.

Other advantages are accomplished with my present invention. asexplainedhereinafter and illustrated in the accompanying drawings, inwhich:

FIG. 1 is a verticallongitudinal sectional view of a spinningframe inaccordance. with my invention wherein a roving or sliver feeding partonly is cut off from outside air;

FIGS. 2 and 3 are vertical longitudinal sectional views of spinningframes in accordance with my invention wherein the roving or sliverfeeding part and drafting part are cut off from outside air;

FIG. 4 is a front view of the spinning frame shown in FIG. 2 partly insection; and

FIG. 5 shows mutual relations of temperature and humidity in thespinning frame in accordance with my invention and those in aconventional spinning frame.

Referring now to drawings, and especially to FIG. 1, numeral 11designates a spinning frame as a whole, numeral 12 is a roller stand,numeral 13 shows a drafting part, and numeral 14 designates a coveradapted to form a chamber 15 enclosing the upper part of the draftingpart 13'. A creel 19 for supporting balling bobbins 18 is mounted in thechamber 1'5. Provision is made of a duct 16 communicated with atemperature and humidity adjusting room (not shown) and provided with anumber of jet holes -17 opened inside the chamber 15. The jet holes 17are adapted to feed air maintained at a temperature and a humidity mostsuitable for spinning into the chamber 15.

It is preferable to use the cover 14 made of transparent resin in orderto facilitate the spinning operation.

It is most desired to add to the roving or sliver about of water by thehumid air fed into the chamber 15. The roving or sliver to which asuitable quantity of humidity has been given becomes about 8.5% in watercontent when drafted at the drafting part 13, so that the roving orsliver can be spun under the most suitable condition.

FIGS. 2 and 3 show other embodiments of this invention wherein thesliver feeding part and also the sliver drafting part are cut off fromthe outside air by means of the cover. In these embodiments, the chamberis formed by a cover comprising a lower section 14 and an upper section14 The lower cover section 14 encloses 3,073,106 Patented an. 1 5, '1963 therein the sliver drafting :part 13 and the upper section 1 1encloses therein the sliver feeding part consisting of balling.bobbins18 (FIG. 2) .or cans 20 (FIG. .3). vPro.- visioni is made of anumber of apertures. 23l-at the bottom of the: lower ecover section 14Theseiapertures 23 serve .toxgui'de the 'drafted yarn towardsspools.24-. The lower cover section 14 is provid'ed at its 'frontrsidewith a.-door -22 adapted to be opened and closed. .-It is preferablethat the upper cover section 14 is also provided with a suitable doorwhich facilitates insertion .and removal of the balling bobbins or thecans.

As mentioned above, thisinvention is intended to provide a;spinning-frame wherein the roving or sliverlfeedin'g part and/ordrafting part are or is enclosed in 'a-cha-mber having asma'll v0lumesuch .that the drafting processmay be effected at a temperature and ahumidity most suitable .for spinning.

Thus, in: accordance with the present invention the. tem- .perature andhumidity existing in-the roving or sliver feeding part and drafting partmay locally be adjustedin .a mostefl'lcient -manner,-so that theinstallation becomes simple and less expensive if compared with. aconven tionalzspinning frame for which temperatureandrhumiditythroughout a largespinning frame room .are to :be sad.- justed..Moreover, v,adherance 'of the flying and dust to sliver :can never beoccurred and .fiuffiness .and break. of yarn can be reduced," therebyobviating frequent clearing of the: spinning frame and rendering themaintenanceand management of the spinningframe" simple and easy. "Likethis way, according 'to the present invention yarn of the highestgrading may be obtained throughout all seasons.

FIGQS illustrates mutual relations of temperature and humidity in aspinning frame inaccordance with-rny invention and thosein aconventional spinning frame.

Table 1 shows results obtained by a spinning frame in accordance with myinvention shown in FIG. 1. The yarn is No. 30s in count.
